Have you had a stroke? How could you tell?
A stroke is a sudden stop of blood supply to part of the brain. Some people have strokes without ever knowing it. These so-called silent strokes either have no easy-to-recognize symptoms, or you don’t remember them. But they do cause permanent damage in your brain.
If you've had more than one silent stroke, you may have thinking and memory problems. They can also lead to more severe strokes.
